[v4,0/2] clk: add assigned-clock-rates-u64

Message

i.MX95 PLL VCO supports rates that exceeds UINT32_MAX, and the
i.MX95 System Controller Management Firmware(SCMI) server exports
PLL VCO for SCMI Agents to configure. So introduce
assigned-clock-rates-u64 to support rates that exceeds UINT32_MAX.
And introduce of_property_for_each_u64 to iterate each u64 rate.

The PR to add assigned-clock-rates-u64 to dt-schema has been merged:
https://github.com/devicetree-org/dt-schema/pull/140

Changes in v4:
- Follow Stephen's suggestion to simplify code for patch 2. Thanks for sharing the
  detailed code
- Note again, patch 1 and patch 2 is not relevant as of now. Just for
  simple for reviewing and know the history, still put them in same patchset.
- Link to v3: https://lore.kernel.org/r/[e-mail]

Changes in v3:
- Add R-b for patch 1
- Rewrite patch 2 to avoid duplicated code. Patch 2 not use code from
  patch 1 now, but since patch 1 is a helper, so keep it.

Changes in v2:
- Follow what Luca did to of_property_for_each_u32 to write of_property_for_each_u64
- Link to v1: https://lore.kernel.org/r/[e-mail]
